Isolation and characterization of polymorphic microsatellite markers from flax (Linum usitatissimum L.)
Flax (Linum usitatissimum L.) is the third largest natural fiber crop and one of the five major oil crops in the world. Flax can be used as model plant for the bast fiber plants because of its small size and self pollination characters. Development of highly polymorphic co-dominant markers will be important for the molecular and genomic research in flax. Two microsatellite-enriched flax genomic libraries...

Development of in planta transformation protocol for wheat
Presently, genetic modification of wheat is carried out through gene gun andAgrobacterium mediated transformation that involves callus phase and is restricted to the tissue culture responses of genotypes. Therefore, a protocol for genetic transformation of wheat without involving tissue culture procedures was established. Imbibed seeds of wheat were sterilized, incised through apical meristem, wounded...

Effect of four herbicides on microbial population, soil organic matter and dehydrogenase activity
The effect of four herbicides (atrazine, primeextra, paraquat and glyphosate) on soil microbial population, soil organic matter and dehydrogenase activity was assessed over a period of six weeks. Soil samples from cassava farms were treated with herbicides at company recommended rates. Soil dehydrogenase activity was measured at four-day sampling intervals up to the 20th day. Bacterial, fungal and...

Development of a mutant strain of Bacillus subtilis showing enhanced production of acetoin
This paper described the screening process of a mutant strain of Bacillus subtilisTH-49 showing specific characteristic and enhanced production of acetoin. The mutant was obtained by treating B. subtilis N-12 with ultraviolet ray (ultraviolet ray (UV)) or nitrosoguanidine (NTG) or compound mutation and subjecting it to a shake flask fermentation selection procedure. The acetoin production rate...

Alkaline thermostable and halophilic endoglucanase from Bacillus licheniformis C108
An endoglucanase was purified from halophilic alkaline Bacillus licheniformisisolated from soils of Lake Van in Turkey. The optimal pH and temperature of the endoglucanase produced by B. licheniformis C108 were 10.0 and 30°C, respectively. The enzyme was highly stable up to 100°C at pH 10.0 and the enzyme retained its complete activity for 6 h in 7 to10% of NaCl. The...

Malt quality of 4 barley (Hordeum vulgare L.) grain varieties grown under low severity of net blotch at Holetta, west Shewa, Ethiopia
Four malt barley varieties (Beka, HB 120, HB 52 and Holker) and 3 fungicide (propiconazole) spray intervals (7, 14, 21 day) and no spray control were arranged in a RCBD in 4 replications to assess net blotch (Pyrenophora teres) effect on malt quality. The varieties were grown at Holetta agricultural research center in 2005, on 12 m2 plot. Grain flour starch pasting and malt qualities were analyzed. Mash...

Combined effects of 1-methyl cyclopropene (1-MCP) and modified atmosphere packaging (MAP) on different ripening stages of persimmon fruit during storage
The aim of this study is to evaluate the combined effects of 1-methyl cyclopropene (1-MCP) applications and modified atmosphere packaging (MAP) to improve the storability of two different harvest maturity stages of ‘Harbiye’ persimmon fruitsduring 90 days storage at 1°C. For this purpose, 1-MCP, an ethylene action blocker was applied before MAP storage....

Effects of some medicinal plants on consumer sensory characteristics of village chicken meat
The objective of the current study was to determine the correlations between the sensory characteristics of village chickens that were treated with medicinal plants. A total of 42 mature village chickens were kept at Fort Cox College of Forestry and Agriculture for 14 days until slaughter. The chickens were randomly allocated to five groups: Group 1 was for the negative control (treated with distilled water...

Volatile compounds of vegetarian soybean kapi, a fermented Thai food condiment
Kapi is a traditional shrimp paste used as a food condiment in Thailand. Several vegetarian soybean kapi, S1-S5, were fermented from various bacterial starter cultures isolated from commercial shrimp paste. The volatile compounds of S1-S5 were analyzed using SPME coupled with gas chromatography/mass spectrometry and compared to three samples of commercial vegetarian kapi (J1-J3) and commercial shrimp pastes...

Antioxidant activities of solvent extracts from endemic Cyclamen mirabile Hildebr. tubers and leaves
In this study, solvent extracts were prepared from different parts of Cyclamen mirabile (CM) and their antioxidant activities were evaluated. Other antioxidant properties of all extracts of CM tubers and leaves, including free radical scavenging activity, reducing power and total phenolic compound content, were also determined. Leaves extracts of CM exhibited higher antioxidant activity than tuber...
